Be it known that l, Rosanne W. Benmnen, a citizen of the United'States, residing at Detroit, in the county of Wayne and State of Michigan, have lnvented certain 'lor the Manufacture of Grape and other Fruit Juices; and l do hereby declare the following-to be a tall, clear, and exact detil hll

scription of the invention, such as will enable others skilled in the artto which it appertains to make and use the same. I

This invention relates to an improved method of preparing grape and other fruit juices by uslng osmotic force or action to extract the juices throu h the cell walls and outer skin of the fruit, mstead of using mecfhanical force as has been practised heretoore.

To carry my invention into eflect, I take any-convenient glass, earthenware, or acid proof enamelwa're container capable of bemg .sealed air tight, preferably one of two gallon capacity, and p ace therein two quarts of caretu 1 selected fruit. To this is added one poun of are granulated sugar, the same being su ciently shaken to distribute the sugar through the fruit. Sulficient water to .fill the container is now' heated to the boiling pointand boiled for. about five minutes, then cooled to about 210 F, at which temperature I add it to the trait and sugar in the container, the same being sealed immediatelyin any well known way, and set aside in a cool place for a time,' 'varying from not less than ninety days to not more than one year, depending upon the variety and ripeness ot the fruit used, and thecolor,

strength, and aroma of the product desired. During this time the osmotic action takes A Specification of Letters Patent. Patqgmmnd tfllmh, 1H1, j1%t application filed March tlflltllll. serial lto. tthttt.

sterile of microbe life, and unimpaired natural color, aroma and flavor.

Having thus described my invention, what ll claim as new and useful, and desire to secure by Letters Patent is: 1. The process out preparing-grape an other fruit juices, which consists in placing the fruit in a container, mingling a rela-' tively large quantity of hot, dilute sugar solution therewith for opening the pores and 'making permeable the skins and cell walls and aiding osmosis,then sealing the container, cooling and subjecting the contents to osmotic action until diffusion or extracting of juice has been efi'ected, then filteringand sterilizing the resulting juices. v

2. The process of preparing grape and other friut juices, -which consists 1n placing the fruit in a container, adding a small proportion of sugar and a relatively large quantity of water at a temperature of a proximately 210 F. for making permeable the skins. and "cell walls and forming a di lute sugar solution to aid osmosis, then sealingthe container andsubjecting the contents to osmotic action in a cool place till difll'usion or extraction of the juice has been effected, then filtering and sterilizing the resulting juice and sealing in a container.

3. The process of preparing grape and other fruit juices, which consists in commingling in a container fruit, sugar and hot water in about the proportion of two quarts of fruit, one pound of sugar and enough water to approximately 210 F. to fill a ltll ' two gallon container thereby forming a and again sterilizin dilute hot sugar solution to make the skins about 160 F. and cell walls permeable and promote os- In testimony whereof I aflix my signamosis, then sealing the container, cooling ture.
